Them look exactly like the power2000 batteries from B&H. I have a power2000 battery (that appears to be the $36 one listed on that first site) at B&H, that I paid $45 for. It's a good battery, they advertise like 3 hours, but I get about 4 hours out of it with the LCD. Thats on my small camcorder though, i'm sure it would be less on your DVX100. You might want to spend a couple more dollars and go with B&H.

Those batteries are not like the Power2000, I'd recommend getting your generic batteries from Ebay if yo REALLY want to save money. The Power2000 is $70 but it's 3600mah, those 2800mah on your sites costs $70. I just picked up a battery from Eagle International, paid $30 for a 2800mah battery.

Please forgive the snobbery, but why would you spend upwards of three thousand dollars on a very nice camera, and then chintz out on the batteries you're feeding it? Why risk a questionable Ebay purchase just to save a few bucks? I don't get it, sorry.

You could get me to buy LenMar third-party batts, but I wouldn't settle for any other brand than that, outside the manufacturer's. You guys are talking about price differences less than $50. Don't you want the best available for the camera you spent so much money on? How many charge cycles are these cheap things good for.

Update: I ordered two batteries from Eagle Importers on Ebay for $29.95 each - appears to be a very reputable company. They shipped same day UPS ground, had them in two days. They charged fine and appear to work just fine - won't know for several months if they run out early.

Chris Hurd: The DVX100 by all accounts is still considered to be a poorman's camera. It's probably the best lowcost solution for many of us. If you can save $30-$50 per battery, then it adds up really quick. I'm planning on buying 2 or 3 more batteries from Eagle Importers, all for under $90. To some extend, it's like buying Eveready batteries over Duracell. Plus if you understand how batteries are made, the generic batteries are no different than namebrands, less the brand of battery cells they used. In this case, it's panasonic cells.

Just dreadful. If this is a defective battery-- it should have never escaped the factory--
sending it back tomorrow and not giving them a second chance. The .8 ounces lighter weight than the Panasonic of lesser mAh was the tipoff.

Panasonic=195 grams, $109 plus tax

Sakar=170 grams, $119 at buydig.com

The Eagle Import battery advertised as 191 grams for $36 includes postage. Will give that a try. search for NEW 3Hr BATTERY FOR PANASONIC DV CAM CGR-D28A on ebay.com from Eagle Imports
Looks like they are being more honest about the expected time life per charge.
